                 The syntax of this parameter in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a
                 single line with the string

                 characters, method <span class="bold"><strong>flag</strong></span>
                 parameter as a string, optionally one or more whitespace
                 characters, and the string <code class="literal">on</code> or
                 <code class="literal">off</code>.  If the optional string is
                 omitted, the default is <code class="literal">on.</code>
